The A60 Hidden Casement system is a part of the window/door system with a thermal break A60. The windows produced from the elements of this system have casements that are unseen from the external side of the building. In the row of adjacent fixed and openable windows all the compartments look the same form the outside . The width of window frames from the external side is small, what makes the structure look slender and light.

  • 3 chamber system

  • Low value of the overall heat-transfer coefficient

  • Structural depth of the window sections is equal to 60 mm (frames) and 69 mm (casements)
